The interior beam frame of the main hall is simple, the structure is rigorous, the nodes are firm, the materials are excellent (the beams, purlins, and bucket arches are all golden silk nanmu), and the components are processed exquisitely.

The nodes between beams and between beams and between beams and columns are generally supported by cross arches to reduce the shear force of the purlins at the head of the beams.

Although the five beams of the main hall themselves are not decorated, the method of adopting the arch body of the two ends of the beam is low and narrow and the middle is high and wide, so that the treatment not only takes into account the load function of the frame itself, but also does not appear to be rough and clumsy because of the large beam.

In the building components, most of the edge contours of the beam head, column head, bucket arch rafter head, flying head, etc. are rolled and killed, and the production rules are regular, and the artistic treatment of each component is carried out by making full use of the easy processing characteristics of the wood itself, so as to better play a decorative role.

Because the main hall was built in the early Ming Dynasty, the beams, purlins, trusses, bucket arches and other components of each beam frame are full of colorful paintings.

Later, with the replacement of the owner of the interior or due to the need for use, the interior ceiling has also changed several times. In the middle of the Ming Dynasty, the beginning of the Qing Dynasty and the middle of the Qing Dynasty, the ceiling was displaced three times, and each time the ceiling was displaced downward, the color paintings on it were retained, so the Zhongcui Palace room not only preserved the swirl color paintings of the early Ming Dynasty and the middle of the Ming Dynasty, but also preserved the dragon and phoenix and the seal color paintings, and also preserved the style color paintings of the outer eaves purlins.

It is rare to leave different historical periods and different styles of color paintings in a palace, which is of great value for the study of the development history of Ming and Qing official color paintings, and is a rare material material.

Yuyan was thinking about things while combing her hair. The Old Summer Palace, also known as the Three Gardens of the Old Ming Dynasty, is a large royal garden of the Qing Dynasty, it is located in the northwest suburbs of Beijing, adjacent to the Summer Palace, composed of the Old Summer Palace, the Changchun Garden and the Qichun Garden, so it is also called the Three Gardens of the Old Ming Palace.

In addition, there are many small gardens, distributed on the east, west and south sides, surrounded by stars and moons.

It covers an area of 3.5 square kilometers, with a construction area of 200,000 square meters and more than 150 scenes

It is known as the "Garden of Ten Thousand Gardens". [2] The Qing Emperor came here every midsummer to escape the summer, listen to the government, and deal with military and political affairs, so it is also called

"Summer Palace". The Old Summer Palace was founded in 1709 (the 48th year of Kangxi), and was originally a gift from Emperor Kangxi to Yinzhen, the fourth son of the emperor.

After Yongzheng ascended the throne in 1722, he expanded the original garden, and added the Zhengda Guangming Hall and the Qinzheng Hall in the south of the garden, as well as many duty rooms of the Cabinet, the Sixth Department and the Military Aircraft Department, and wanted to be here in summer

"Avoid noise and listen to politics". During the reign of Emperor Qianlong, in addition to the partial addition and reconstruction of the Old Summer Palace, the Changchun Garden was newly built in the east and merged into the Wanchun Garden in the southeast.

[3] The pattern of the Three Gardens of the Old Ming Dynasty was basically formed. In the Jiaqing Dynasty, the Qichun Garden (Wanchun Garden) was mainly repaired and expanded, making it one of the main garden places.

During the reign of Emperor Daoguang, the state was declining and the financial resources were insufficient, but he would rather withdraw Wanshou, Xiangshan, and Yuquan

The furnishings of the "Three Mountains", the summer retreat of the Rehe River and the hunting of Magnolias, still do not give up the reconstruction and decoration of the Three Gardens of the Old Ming Dynasty.

On October 6, 1860, the British and French troops ransacked the Old Summer Palace, looted cultural relics, burned them, and wanted to restore them when the Tongzhi Emperor wanted to restore them, but due to financial difficulties, they were forced to stop and rebuild other buildings.

After the Eight-Nation Alliance, it was attacked by bandits and finally turned into a ruin. The Old Summer Palace, founded and operated by the Qing Dynasty for more than 150 years, has been famous for its grand regional scale, outstanding construction skills, exquisite architectural scenery, rich cultural collections and profound national cultural connotations

"A model of all gardening arts", praised by the French writer Victor Hugo

"A model of ideals and art".
